我正在使用Beautiful Soup 3解析一些HTML,但它包含HTML实体,Beautiful Soup 3不会自动为我解码:

>>> from BeautifulSoup import BeautifulSoup

>>> soup = BeautifulSoup("<p>&pound;682m</p>")
>>> text = soup.find("p").string

>>> print text
&pound;682m

我怎样才能解码HTML实体中text获得"£682m",而不是"£682m".

我正在做一些网页抓取,网站经常使用HTML实体来表示非ascii字符.Python是否有一个实用程序,它接受带有HTML实体的字符串并返回unicode类型？

例如:

我回来了:

ǎ

代表带有音标的"ǎ".在二进制中,这表示为16位01ce.我想将html实体转换为值 u'\u01ce'

尝试在 Pycharm 中创建新的 python 3.9 Virtualenv 环境时，我收到了这样的错误

AttributeError: 'HTMLParser' object has no attribute 'unescape'

可以用它做什么？
